The issue is consistency and I'm perhaps not using the terms precisely enough
to describe what I am seeing.
I understand about MIDI notes and that they are neither sharpened not
flattened, but each has their own value.
In my sequencer (Cakewalk ProAudio 9), if my piece has a Key Signature event in
the .MIDI (I'm not talking about a Cakewalk format file) file of "G", I see a
staff with an F sharp at the beginning of the staff and no sharp signs on Fs in
the piece.
When I create MIDI output from Lilypond, if I have imported a MIDI file and
then resaved it with changes made in LilyPond, the output is like that, too.
However, when I create new files, I am getting output that is as if I have
chosen to write everything in C major, with all the flats and sharps shown
explicitly. Nevertheless, the screen and pdf output are written in, for example
G, with no sharps on the individual fis notes.
So ,what appears to me to be happening is I have written code that works for
layout {} but just this aspect of it is ignored by midi {}
But I am new to LilyPond so that deduction may be nonsense. I have much more
experience of MIDI files and have been using the same software for many years
and am aware of its idiosyncracies.
In LilyPond, I have other similar issues which suggest to me I am making a
bigger, more fundamental mistake in my coding, so I will investigate that
before asking for any more help and in that case I will bring the necessary
snippets to the forum.
Thanks for your interest.

Yes - and it's not Lilypond that does that step, so if the translation
back to staff notation is not as desired, there's little that can be done
within Lilypond to fix it.
